Magnesium Stearate and the Pescatarian Diet

Magnesium stearate is a salt composed of magnesium and stearic acid, commonly used in supplement and pharmaceutical manufacturing as a flow agent to prevent ingredients from sticking to equipment. Stearic acid can be sourced from both animal fats and vegetable oils, making the origin of magnesium stearate a concern for vegetarians, vegans, and certain other dietary practices. However, versions of magnesium stearate derived solely from vegetable sources are available and are often labeled as such.
